Receives "name 'Dfu' is not defined" from Master Control Panel

[jokii]

Hi I'm trying to perform update (DFU) of my application using Master Control Panel 3.10.0. I'm connecting, discover services (see DFU service available), then press "DFU" button, choosing zip package or hex to update, click to start, but update fail with following log message:

5365;10:41:34.8425 [680333028][] name 'Dfu' is not defined

Using nRF Conenct, or nRF Toolbox from mobile app (Android, iOS) to DFU works fine.

Is there are any additional requirements to do DFU by MCP?

Are you using SDK v12.0.0?

I'm using SDK v10.0.0 and I'm not going to move to 12, since project is finished and tested 99%. Dfu process seems even not start.

DFU with MCP should work just fine with SDK v10.0.0. I have never seen this type of error before. Have you tried to uninstall and re-install MCP? If that does not work, then you can try to downgrade your MCP version, you can find older versions here.

Reinstallation ("Repair" option) fix issue. Thanks
